This is going to be a bit long XD
First of all, he is most certainly one of my ultimate biases in life. Woohyun is hard-working, talented, and mischievous as any Inspirit will know.
However, I think that he is also eager-to-please. He seems to put a large weight on what other people think (as is obvious with his constant checking that what he’s saying/doing is not over stepping the bounds - particularly with Sungkyu) What do I mean? Woohyun will glance at Sungkyu to gauge his reaction whenever he teases his hyung - practically EVERY time he does it
Next point: Idealistic. Woohyun seems to be a dreamer, and a romantic. I think that he has romanticist views about love and relationships in particular, which is cute and can be sweet but also means that he would be really naive, and innocent in that he would make pretty dumb decisions to keep his lover with him which could end up really hurting him.
I think Woohyun is also very stubborn/hard-headed, and a little bit ego-centric (which isn’t a bad thing and honestly should be expected with ALL celebrities). He seems to be a proud kind of man, which means that he would not take well to be told what to do. I actually think he’d rebel against it whenever and wherever and as often as he could - just to make a point.
Which brings me to my next point: a little bit selfish. This isn’t a bad thing as long as it’s kept in check, I think this would stem in most part from the idealist view of love. He’d have expectations that I think would be pretty hard to fill. Not physically necessarily, but definitely with how his partner would be expected to be in a relationship.
I have no doubt that he is an optimist. Maybe not all the time, but I think he’d always try to look for a solution, a silver lining, and would try to stay positive.
I think that he would need consistent reassurance in some areas in his life. A constant reminder that he is enough, and that he is doing a good job.
I think that he could struggle with feelings of jealousy. I’m not sure why I think that though =| He’s also rather touchy with people he cares a lot for. SKINSHIP~ XD
HIS CUTE STAGE PERSONA IS EXACTLY THAT - A PERFORMANCE! Not saying that he wouldn’t be cute in day-to-day life, but he definitely doesn’t run around throwing hearts at his managers and members all day, everyday. In fact, I think that the only time he does is when there are cameras or fans around =D
To sum it all up: he is a normal young man growing into himself =)
